Use a centralized logger (like Winston or ELK Stack ) so you can see exactly where a packet dropped within the hub's logic. 5. Final Deployment & Scaling
Building a server-side hub is about moving from "direct communication" to "orchestrated communication." By centralizing your logic, you make your entire ecosystem easier to monitor, secure, and scale. How To Make A Serverside Hub Part 2/2
If you are using WebSockets, ensure your load balancer supports "sticky sessions" so a user stays connected to the same hub instance during their session. Conclusion Use a centralized logger (like Winston or ELK
Start by implementing a simple Redis cache to see how much it improves your hub’s response times! If you are using WebSockets, ensure your load
This second part of our series dives into the of your server-side hub. If Part 1 was about setting the stage (infrastructure and basic routing), Part 2 is about making the gears turn—handling data persistence, real-time synchronization, and security.
Since the hub is the central point of contact, it is also the primary target for attacks.
